A sentence describing a spatial relationship includes at least two objects: a located object and a reference object. However, when we indicate a located object with respect to a reference object using a spatial term, the scene usually contains extra objects that may look like the located or reference object in some cases. What role do such extra objects play on the apprehension of spatial terms...
18F-labeled N,N-diethyl-2-(2-[4-(2-fluoroethoxy)phenyl]-5,7-dimethylpyrazolo[1,5-α]pyrimidine-3-yl)acetamide (DPA-714) is a radioligand for the 18-kDa translocator protein. The purpose of the present study was to identify the best method for generating quantitative parametric images of 18F-DPA-714 binding. METHODS Ninety-minute dynamic 18F-DPA-714 PET scans with full arterial sampling from 6 ...

At the beginning of 1998, Griffith University opened a new campus in Logan. In order to provide a breadth of study opportunities, and to expand access opportunities to those who are unable to attend the campus regularly, the University offers subjects at Logan through flexible modes of delivery. The Logan teaching and learning environment includes a range of approaches to flexible learning. In ...
We use Karchmer and Wigderson’s recent characterization of circuit depth in terms of communication complexity to design shallow Boolean circuits for the counting functions. We show that the MOD, counting function on n arguments can be computed by Boolean networks which contain negations and binary ORand AND-gates in depth c logrn, where c A 2.881. This is an improvement over the obvious depth u...
